Conflicting Speed test

Hi ORBINEWBIEUK

I'm really intertested in your results, because it mirrors my own experience per this thread a week ago:   Orbi Throttling Speed

I tried two different routers along-side the Orbi (a Linksys E8500 and the ISP-provided Huawei HG659) and I got consistent results.  Using the Linksys or Huawei I got full speed of 200 Mbps.  Using the Orbi, I got between 107 to 37 Mbps.  My speed typically averages aound 70 Mbps, but can drop as low as 40 Mbps and as high as 140.  

The Orbi reports the full 200 Mbps speed into it (it has a internal speedtest at "Advanced", "Setup", "QoS Setup").

st_shaw was trying to be helpful in response to my thread, but all his/her suggestions missed the point from my testing:

• It was not a "failure of my computer's NIC to autonegotiate speed".   Back-to-back tests using the exact same set up (cables and the test PC) consistently returned the same results - Orbi slow, the other two routers full speed.

• It was not a "bad cable".  Despite trying different cables (to eliminate this potential cause) before I did the back-to-back testing with the same setup, the results were - again - consistent.

• It is not "different tolerances for marginal cables, so it could still be a cable or port issue".  As I mentioned, I tried different cables (all Cat 5E and Cat 6) and the fact that the two other routers were not affected disproves this theory (unless the Orbi's 'Internet' port is faulty, but it reports 200 Mbps in, so unlikely ...). 

I note that you're in UK.  I'm in New Zealand on Vodafone using their 'FibreX' service which is not true fibre. FibreX uses DOCSIS3.1 / DHCP and VLAN10 tagging.  My suspicion is that the Orbi doesn't play nicely with this architecture.
